PAPER FEEDING AND SEVERIN G MECHANISM.

- Application filed February 27, 1913.

To all whom it may concern:

Be it known that I, ALBERT KRAUTH, a citizen of the United States, residing at Hamilton, in the county of Butler and State ofOhio, have invented certainnew and useful Improvements in Paper Feeding and Severing Mechanism, of which the following is a specification.-

My invention relates to paper feeding and severing mechanism in which invariable constant lengths are successively advanced and severed from a continuous sheet, I

The severing mechanism herein .disclosed is in close proximity to the feeding mechanism so as to reduce the spacing interval dividing the text lengths to a minimum, and the feeding and severing accomplished in a continuous cycle of a manually operated The paper feeding mechanism becomes dormant after the prescribed advancement of the paper, with the severanee of the paper progressively followed in each manipulating cycle, and provision is made for absolutely determining the cycle by positively limiting its progress.

One objectof my? invention is to provide a pair of cutter members, one having its cutting edge longitudinally spiral and circumferentially movable so that its edge will progressively engage in a tangent plane with the cutting edge of the second cutter relatively stationary and in a diametric plane with the axis of said movable cutter member. The movable cutter member in its cutting direction of paper feed and thereby avoids any paper pulling action which may have a tendency to displace the alinementbetween several sheets simultaneously fed in text registry.

Another object of my invention is to pro vide an oscillating cutter member with its cutting edge movable progressively in a transverse'plane across thecutting edge of a relatively stationary cutter member yieldingly urging its cutting edge in a diamet- II'IC plane toward the axis of the oscillating cutter member.

Another object of my .invention is to combine paper-feeding and paper-severing mechanism arranged in close proximity. to each. other and with the cutting mechanism operated intermittent to operate after a prescribed interval of paper feed so as to sever a continuous sheet into constant in-.

- variable lengths. In the disclosure herein the prescribed interval length and severance is accomplished in a complete singlecontinuous revolution of a crank handle, with provision made definitely determining the limit of a revolution, orcycle, requiring manual release for a successive operation. This absolutely determines the length of interval delivery in relation to a fixed text arrangement preprinted upon the continuous sheet, in successive multiple numbers, for an invariable constant length successive delivery. The feed matically discontinues in advance of the operation of the severing mechanism in each cycle of the crank handle. The features of my invention will be more fully disclosed in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a mutilated side elevation of the forward portion of a manifolding apof the paper autosevering and feeding mechanism with parts.

These side frames may be of two-part form, with the forward portions unitarily connected and swingingly mounted, adapting the same to be swung upon the rear portions of the side fpames for convenient access to the supply webs of paper, such construction being common in machines of this type, but for the purposes herein'are each shown as of a single unit.

tion oftheapparatu's.

It is desirable to advance the continuous within a complete rotation of the crank handle in a'manualoperation of the machine an within -such cycle of operation, and' to ard the limit thereof discontinue the feed following with a; severing operation for separating the ad-- vanced endlength from the continuous sheet or strip, the feeding and ,seve'ring operation a being all accomplished with a deiimte cycle of crank handle manipulation, after which the crank handle is arrested but ;.is capable of being rel for a sucwssive operation. This, however, is only essential or when one ormore of the continuous stripsare subdivided into equal interval lengths, with the severance made at a point-separating the intervals so that an improper orance cannot be made, as would occur'i the crank handle were free to be continuously rotated without interruption. I 11 represents a lower paper feeding roll having itsaxle-12 journaled in the side frames 2,3, with a gear 13 fixed at one, I end of the axle 12,, inside of the casing 2 formed by the side frames. The gear13 is in mesh with a pinion 14 fixed upon the axle 1,5, which carries the upper feeding roll 16. The upper feeding roll is journaled in slide blocks 17 slidably mounted in wags, one formed in each of the side frames, or yieldingly jou'rnaling said upper feeding roll so as to urge its periphery into engagement, or toward the periphery of the lower feeding roll, for impingedly or frictionally'engaging thefpaper threaded between said rolls to propel or advance'thepaper upon rotation of the rolls. The gearing for said rolls positively rotates the same in relative reverse directions to preventany slippage of the upper roll or movement in a'direction reverse .to the travel of the pa r.- This construction of paper feeding r is however well-known in the art, andcomprises the most substantial and efiicient form of paper feeding mechanism for use inmanifolding devices, and in the term pa rfeeding mechanism analogous or equiva ent constructions are herein comprehended.

The axle15 oi -the upper feeding roll has a, pinion 18 fixed thereon, preferably exter or of the sideframe 2, see Fig. 3, which intermeshes with-a mutilated gear 19fixed upon the shaft 20, the shaft 20 extending I frames and journaling therein. The gear 19 has a portion of its teeth cut away, so that tho'feeding rolls will be its severance operated of themachine,

' handle 23 is fixed. mounted within a lug 25- shown in o ght t e me ng an int rval 'a a complete rotation of gear 19 to stop the paper feed for a subsequent operation of paper severing mechamsm within a cycle or one complete rotation of'the gear 19, or to bring the paper advance to rest during a severing interval. In the construction dis closed, an interval advance of the paper and contemplated within one'cycle of'the crank handle. Such'ope'ration, however, p w: the advantage iii-certain particular uses, and I- do not wish to be limited herein to'fthe V trol and operation-of the paper feeding and se *mechanismswithin a' cycle orprescribed .movement of the nism, nor-do I 'wish to discontinuance of feed during a paper severing operation,- for it is obvious that the paper cutting instrumentalities could be under an accelerated movement over the feed or advahceof the paper without interference.

handle aftereach 'com anism herein illustrated comprises an 08011 lating knife ting edge in a angular longitudi engage, with the lo diametric plane, and spiral orlly so'asto pro ressively gitudin'al straight edge of a companion cutter baryieldingly urged toward the oscillating cutter bar or knife. The cuttingedge of the stationary cutter bar is-in bar having its longitudinal cut- 1 a diametric plane with the axis of rotation or oscillation of the movable cutter blade, producing a shear action from one end of the cutter bar toward the other. The aper is fed between the cutter members wit the rear portion of the stationary cutter inclined upwardly to offer clearance for the pa per and guide the same between the cutters. The rearward circumferential portion of the oscillatin cutter member is also provided with re ief, and by reason of its spirality, the two cutter members progressively engage in a diametric line from the axis of the oscillating cutter. This has self-shar ening tendencies and avoids mutilation of tie cutting edges.

"he lower cutter, as above referred to comprises a cutting bar 27 having a spiral bend longitudinally from one end to the other by twisting the bar slightly with the cutting edge 28 in a straight plane throu hout its entire length and relieved rearwardly from such cutting edge as shown at 29, see Fig 2, so that only the cutting edge engages with its companion cutter bar, when a comparatively thick cutter bar 18 employed.

30, 30 represent annular flanges at the ends of the cutter bar having a radius dimension substantially equal to the distance of the cutting edge from the axial line of the cutter, upon which the ends of the stationary cutter travel, to prevent the same from moving beyond the cutting are of the oscillating cutter. These flanges serve as guides for the stationary cutter in its normal position.

31, 31 represent pintles projected beyond the flanges, providing an axis for the oscillating cutter. They are journaled m the side frames 2, 8, and preferably project beyond the side frame 8, to fixedly receive the toothed quadrant 82, its teeth 33 bein adapted to be intermeshed with the teeti :H of the uc ment pinion 35 fixed upon the shaft .20. "he toothed intermesh s relatively arranged and timed to become effective during the inoperative interval of the feeding rolls when the gear 19 at its cutawav toothed portion is tangent with the circumference of gear 18.

As shown. the oscillating cutter is operative toward the limit of rotation of the crank handle in a paper feeding cvole, after the requisite feed of the paper. The oscillating cutter is rocked or rotated rearwardlv to its normal position automatically, the spring 852' has one end thereof fixed to the side frame 3, with the opposite end to the arm of the quadrant, or toothed lever.

As shown in the drawings, the segmentallv toothed. pinion 35 has but two teeth, which in a feeding evcle with the crank handle movingtowarcl the right, as shown by arrows, will not engage the teeth of the lever 32 until after the feed of the feeding rolls has been discontinued. As soon as the teeth of the segmental pinion 35 pass the last tooth 83 or the lever 32, the lever will be free to be oscillated to its normal position. The normalizing movement of the oscillating cutter bein in a direction of the feed or advance of t e paper and therefore will not interfere with such advance, should a successive interval advance of paper quickly follow.

36 represents the stationary cutter having its cutting edge 37 disposed in a diametric plane longitudinally with the axis of the oscillatin cutter and the rear portion thereof provided with relief. This cutter is slidably mounted in ways formed in each of the side frames with a spring 36' housed in each of the side frames engaging the stationary cutter to ur e the same downwardly toward the axis of the oscillating cutter. The tension of the springs can be adjusted by the screw 87.

The upper portion of the stationary cutter is arced or angled toward the tangent line of the feeding rolls so as to enable the paper to be fed over the same and delivered from the machine and severed by pulling the same over the knife edge of the housing 39, inclosing the feed rolls, or the paper could be severed manually by pulling the same upwardly from one end against the cutting edge of the stationary cutter.

40 represents a table fixed to the side frames and projecting beyond the forward portion of the apparatus to receive the severed length, and the forward portion of the table may be provided with a notch, for readily grasping the paper.

41 and 42 represent pawl and ratchet mechanism for preventing reverse action of a crank handle. the ratchet wheel 41 being fixed to shaft 20.

4-3 represents a lever one provided adiaeent each of the side frames and pirotally mounted upon the axle or sha'l't 1-2 of the lower feed roll, one arm of each lever adapted to engage at opposite ends with the axle 15 of the upper feed roll for raising the same to release the frictional engagement of the feeding rolls and separate the same to eonvenientlv thread the paper between said shafts. The lovers are actuated bv rock shafts 44 manually accessible from the exterior of the machine by the lever arm 45.

The essential features to which my invention is primarily directed is in the provision of a pair of coacting cutters, one having oscillating motion, the second stationary relative to the oscillatory movement of its companion cutter but yieldingly urged toward the same, its cutting edge longitudinally diainetric with the axis of the longitudinal spiral oscillating cutter, to provide a. progressive continuous cutting action transversely across the paper, and when combined The toothed lever 32 engages an adjust-- able stop to limit its normalizing movement, comprising an eccentric collar 46 adjustably secured to the side frame 3 by a screw 47,-

see Fig. 1. This also provides for the proper coiiperation of the'teeth 33 and 2 34 of the lever 32 and segment pinion 35.
